Tanya Chapter 21, Class 4 (163). This class begins the other side of the coin. So far in Perek 20-21 the issue has been Achdus Hashem and we go from lower to higher; now begins the point of of “יע וועלט” there is a world (in some ways that is very important for Torah and Mitzvos (and out free will) and reward and punishment to be true. We begin discussing ‘worlds’ on levels of Godliness; where (though we are accepting the Tzimtzum as real [from our point of view]) we are dealing with worlds that are Godly, in other words, they are true. In Chapter 2 he’ll discuss Klipa (worlds) that are a lie. Our existence is through Machshava Dibbur and a second Dibbur which is like Ma’aseh (the idea of Hislabshus Koach HaPoel BiNifal).
